I think that's the single best piece of advice: constantly think about how you could be doing things better and questioning yourself.
I think that's an important thing to do, to really pay attention to negative feedback, and solicit it, particularly from friends. This may sound like simple advice, but hardly anyone does that, and it's incredibly helpful.
I've always wanted to be part of something that would radically change the world. . . . People forget the power of inspiration. All of humanity went to the moon with the Apollo missions. The issue was cost. There was no chance to build a base and create frequent flights. That's the problem I would like to solve.
Every mode of transport that we use - whether it's planes, trains, automobiles, bikes, horses - is reusable, but not rockets. So we must solve this problem in order to become a space-faring civilization.
